Removed bogus threading test to make TSAN happy.
...
TSAN hits an internal assertion on a self-join, and the test is not
really that useful, so let's just remove it.

Steps towards unification of number bitset and range types.

- New invariant on union types: if the union has a range then the number

- Various tweaks in intersection and union to satisfy the invariant.
- Exposed and used representation bits in range types (and the Limits
helper class).
- Implemented Glb for ranges so that the Is predicate handles

- Change typer weakening so that it does not rely on GetRange.
However, the code still seems to be a bit fragile.
- Removed the Smi types from the type system core, instead introduced
Signed31, Unsigned30 and created constructors for Small(Un)Signed
that point to the right type for the architecture.
- Punched a hole in the config to be able to get to the isolate so
that it is possible to allocate heap numbers for newly created
ranges.

ControlReducer only runs really early and really late in the pipeline

phi/select elimination.

FINAL implies OVERRIDE, which in turn implies virtual, so there's no need to use
more than one of these. The Google C++ style guide even requires this, see
http://google-styleguide.googlecode.com/svn/trunk/cppguide.html#Inheritance .
While we're here, port r24662 to x87.
The net result is that v8 compiles again with a current clang.

Fix bugs in simplified lowering relating to int32/uint32 signs.
...
Lowering of NumberToUint32 and NumberToInt32 was not correctly accounting for the sign of the input and the sign of the output, emitting the wrong representation changes.
Along the way, I've found cases where MachineOperatorBuilder would break if fed a machine type for loads or stores that was not cached, requiring MachineOperatorBuilder to take zone to allocate operators for these cases.

Better typing and type verification
...
- Extend verifier to check types of JS and Simplified nodes.
- Untyped nodes now contain NULL as types, enforcing hard failure.
- Typer immediately installs itself as a decorator; remove explicit decorator installation.
- Decorator eagerly types all nodes that have typed inputs
(subsumes typing of constant cache, removing its typing
side-channel and various spurious dependencies on the typer).
- Cut down typer interface to prevent inconsistently typed graphs.
- Remove verification from start, since it caused too much trouble
with semi-wellformed nodes.
- Fix a couple of bugs on the way that got uncovered.
To do: verifying machine operators. Also, various conditions in the
verifier are currently commented out, because they don't yet hold.

ES5.1 section 6 ("Source Text"):
"Throughout the rest of this document, the phrase “code unit” and the
word “character” will be used to refer to a 16-bit unsigned value
used to represent a single 16-bit unit of text."
This changed in ES6 draft section 10.1 ("Source Text"):
"The ECMAScript code is expressed using Unicode, version 5.1 or later.
ECMAScript source text is a sequence of code points. All Unicode code
point values from U+0000 to U+10FFFF, including surrogate code points,
may occur in source text where permitted by the ECMAScript grammars."
This patch is to reflect this spec change.

Relax representation requirement in FrameStates.
...
This change enables non-tagged representations in FrameStates.
That allows us to run zlib with deoptimization support and have almost the same performance of the generated code (as the code with no deoptimization). Unfortunately, the frame states seem to confuse typer. As a consequence, we generate more representation changes, which in turn causes the scheduler to take a lot more time and memory (>4x). The added compiler time makes zlib with deopt be about 50% slower.

[turbofan] Drop broken StaticParameterTraits.

The StaticParameterTraits are broken by design, and cause way too much
trouble. The compilers usually pick the wrong specialization (i.e. the
default specialization is picked for Load and Phi even tho there is a
specialization for MachineType), which is not only the reason why GVN is
ineffective and slow, but can also lead to correctness issues in some
rare cases.
Also clean up some minor bugs/inconsistencies on the way.
